When using "notional number", clearly define the context in which the number is being used and explain why it's notional rather than a precise value. For example, explain that it's an estimate or a figure used for illustrative purposes.
Common error
Avoid using "notional number" when a precise figure is available or required. The term suggests approximation, so if accuracy is paramount, opt for a more definitive term. For example, specify the exact number.
